4-Orange Company holds a loan with an interest rate of 6.00% compounded quarterly. Calculate the effective rate of the loan.
Answer to Question 1:
Monthly Deposit = $270
Time Period = 6 years or 72 months
Annual Interest Rate = 3.70%
Monthly Interest Rate = 3.70% / 12
Monthly Interest Rate = 0.30833%
Accumulated Sum = $270*1.0030833^71 + $270*1.0030833^70 + … +
$270*1.0030833 + $270
Accumulated Sum = $270 * (1.0030833^72 - 1) / 0.0030833
Accumulated Sum = $270 * 80.479362
Accumulated Sum = $21,729.45
Total Deposit = 72 * $270.00
Total Deposit = $19,440.00
Total Interest Earned = Accumulated Sum - Total Deposit
Total Interest Earned = $21,729.45 - $19,440.00
Total Interest Earned = $2,289.45
Answer to Question 2:
Annual Interest Rate = 3.63% compounded quarterly
Quarterly Interest Rate = 3.63% / 4
Quarterly Interest Rate = 0.9075%
Effective Annual Rate = (1 + Quarterly Interest Rate)^4 -
1
Effective Annual Rate = (1 + 0.009075)^4 - 1
Effective Annual Rate = 1.036797 - 1
Effective Annual Rate = 0.036797 or 3.6797%
Semiannual Interest Rate = (1 + Effective Annual Rate)^(1/2) -
1
Semiannual Interest Rate = (1 + 0.036797)^(1/2) - 1
Semiannual Interest Rate = 1.018232 - 1
Semiannual Interest Rate = 0.018232 or 1.8232%
Nominal Interest Rate compounded semiannually = 2 * Semiannual
Interest Rate
Nominal Interest Rate compounded semiannually = 2 * 1.8232%
Nominal Interest Rate compounded semiannually = 3.6464% or
3.65%
